It says the value I assigned isn't right, but how come？

As mentioned above

Temperature.swift 
class Temperature {
    var celsius: Float = 0.0
    var fahrenheit: Float {
        get { return (celsius * 1.8) + 32.0}
        set { celsius = (fahrenheit-32)/1.8 }
    }    
}

Hi Runsheng,

The fahrenheit inside the 'set' is not valid, you need to use 'newValue'.

set { celsius = (newValue-32)/1.8 }
